The SpectrSpan is an optically pumped, single-mode VCSEL operating in the 1550-nm range and tunable over a full ITU band (C or L) with 50-GHz spacing. Microelectromechanical technology enables rapid, continuous tuning, providing circuit-restoration performance for end-to-end transmission at the optical layer. Optically pumping the device achieves the output powers required for primary sources in metropolitan and long-haul DWDM systems. The device uses a single voltage-tuning circuit, with virtually no power consumption, and is housed in a 14-pin butterfly package. It is available on a standard board, which provides the complete tuning and locking circuit.
